Oh, now I understand what you were after. I'd say, "You finally got here". No have. Under certain circumstances, say I was waiting to introduce a belated speaker to an audience, I might say, "Oh good, you're here". ARE, not have (come). Nobody "arrives" where I am--someone can arrive at their destination--as long as that destination is not my location. This isn't a rule or anything. But I, and every person I know here, would think it odd to be told, "you have arrived" or "you finally arrived". Even when someone was telling me about a trip, I'd be more likely to say, "Did you get there on time?" than, "Did you arrive on time?". But if your research must include the word arrive, then it would be "You finally arrived". Hope this helps, Sweetie.
